I administer a group of descendants of Vaughans who have conducted quite a few Y-DNA tests and we are in the process of charting our ancestry. One of our new test subjects is an elderly man who takes blood thinner and while doing the cheek swab today his cheek bled some and he got blood on the swab. I know blood has Y-DNA in it, but I was unsure if this would mess up the test. He hasn't done the second test yet, and will try to be careful, but I wanted to find out before he does the second test.
